Recovering Multiple Nonnegative Time Series From a Few Temporal Aggregates

5 Oct 2016Jiali MeiYohann De CastroYannig GoudeGeorges Hébrail

Motivated by electricity consumption metering, we extend existing nonnegative matrix factorization (NMF) algorithms to use linear measurements as observations, instead of matrix entries. The objective is to estimate multiple time series at a fine temporal scale from temporal aggregates measured on each individual series... (read more)
